What do you mean ? What sort of database ? If it's a SQL Server DB, then the app does not connect to it through the file location, but through SQL Server, so you would still need to mount it and get your connection string configured right. Some more detail will help us to provide a better answer, pls edit your post and add info like what the DB type is, your connection string, etc.
